• SQL Server Problems with performance when programmatically printing large amounts of pages

  We are using VB.NET 2005 to develop a WinForms application that uses SQL Server 2005 Reporting Services to produce reports. Originally we tried  using code found on Bryan's WebLog,  http://blogs.msdn.com/bryanke/articles/71491.aspx , but found that for reports of 300 pages it was taking about 2 minutes to render each page. When using RenderStream to render idividual pages, reports of about 20 pages printed without a problem, but for reports of 300 pages we recieved the follwoing error: "The stream cannot be found. The stream identifier that is provided to an operation cannot be located in the report server database." Is there some cache or something that we should be using Any ideas appreciated. -- Leah The ...Show All

• Software Development for Windows Vista Adding roles to WorkflowRoleCollection

  Hello, I'm developing a workflow with ASP.NET authentication. I have assigned some event handlers in the workflow a WorkflowRoleCollection in their Roles property. When I want to fill the WorkflowRoleCollection with the roles that can raise the event, apparently I don't do it right. The problem is that when I raise that event I get an exception saying something like "authorization error in eventhandler guardaHorari1", and by checking the exception details I've thought that the problem is that when it checks the role of the user that tries to launch the event agains the workflowrolecollection, it doesn't find it there. I fill the collection this way: public WorkflowRoleCollection rolsModificadors = new WorkflowRoleCollection(); ...Show All

• Software Development for Windows Vista reading event log; compatibility xp and vista

  I have posted this on the vista sdk forum. As this is also a compatibility issue, I am posting this on the compatibility forum also. I have an application in unmanaged VC++ working successfully on XP. However when I run the application on vista I get errors. The application creates an event, and uses the NotifyChangeEventLog sdk function to notify my application of any new event being written to the windows event log. I then use the ReadEventLog to read the event log record. All these functions are supported on the Vista and works fine. However, things get murky hereafter for the vista. I use the registry to read the EventMessageSourceDLL which then provides me the event description. However this part is not working on Vista, ...Show All

• Windows Live Developer Forums drawing lines/polygons on map with line following pointer?

  hi, i have successfully created an app where a user can click on the map and draw lines and polygons. each time the user clicks, it creates a node and a line is drawn from click to click with an attachevent onclick function. however, i noticed how on the maps.live.com site, when you draw a line and click on the map, and you move your pointer, a line follows the pointer nicely, giving the user a great sense of where the line will be drawn before he actually selects the next node. would anybody know how this is done many thanks No its not in there. Yavuz should be credited with working this one out. There are two lines that are undocumented in the SDK:   map.AttachEvent('onmousemove', mapMouse ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rants on XNA 1.0

  This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the contents are only built before the program runs. The helper functions wrapping D3DX can only be used with types in the content pipeline. I have to utilize the full content pipeline just for generating something dynamically, of course with significant performance cost. Or I have to write those D3DX utilities my self. Currently I don't have a good id ...Show All

• Windows Live Developer Forums Announcing v4 - 3D Mapping!

  Announcing v4 - 3D Mapping! Today at 2PM (PST) we launched v4 of the map control, and with it some pretty amazing additions to the VE mapping world. You can read all of the blogs and marketing materials (and of course, go to maps.live.com) to get all the “wow” stuff. Here I just want to highlight what I think matters to VE developers. The Good First, we also updated the v3 control (now, v3.2). The big change here—and this is also in the v4 control—is the ability to now turn off the location disambiguation dialog and easily build your own. Check the “Finding Information” topic in the SDK. The iSDK also shows how to do this, of course. The Great On to v4: The big change, of course, is that you can now sho ...Show All

• SQL Server filter one one dataset with values in another dataset?

  Hi, I have two datasets in my report, D1 and D2. D1 is a list of classes with classid and title D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1. I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table. Is there any way to do this in RS2005 Put everything together in one single dataset, group by classid. Use a left inner joing for the dataset. It's a little technical but it can be done. ...Show All

• .NET Development Percentage Sign in DataTable.Select()

  I'm using the Select method of the DataTable in .Net 2.0 in order to return a DataRow[] which match a set of criteria. One of those columns contains strings and I want an exact match. The filter parameter of the Select method seems to use a SQL-like syntax where % acts as a wildcard character. However, it's possible for the value of the string to contain a percentage sign. Using the SQL rules solved an earlier issue I had with an apostrophe (I escaped the single apostrophe into a double apostrophe). However, nothing I try seems to convince the Select method to treat my percentage sign as a literal character instead of a wildcard. I've tried [%], \%, %% , but no luck. Both the Select() method and Expression property documentation in t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. texture fetch and shader math execution time in special cases

  Hi, when I do successive texture fetches using the same texture coordinate, without doing any other texture fetches in between (doesn't seem to make sense, yeah, but it does in my context :)), does it mean the value I receive is already in the texture cache And is the tex. fetch thus quicker than a random location texture fetch Another question: when I do some mathematical computations in a pixel shader and one operand is always 0 so that the result is 0 as well, are these computations executed quicker than in the case when the operand is != 0 so that the computations actually have to be executed to receive the result Best Regards Nico It isn't really a precise science unless you know a lot about the t ...Show All
